摘要

Iron is the most common impurity in hydrometallurgy which is usually removed by precipitation of insoluble iron compounds, such as hematite and jarosite. The knowledge of iron solubility in multicomponent solutions is important for design and optimization of the iron removal steps. The OLI Software package is a chemical modeling tool that incorporates the powerful mixed-solvent electrolyte (MSE) model capable of performing simulations of multicomponent electrolyte solutions from the freezing point up to the limit of fused salt and near the critical temperature of the solution. Literature or experimental solubility data was fitted on the OLI MSE model to improve the performance in simulating multicomponent Fe(II)/Fe(III) solutions. The particular focus of this work aimed at developing simulation capability for the FeCl 3-MgCl2-HCl-H2O system through experimental solubility measurement and modeling, relevant to atmospheric processing of saprolites by HCl using MgCl2 brines.
